When all four wings unbolt, the engine comes out in under an hour, there’s no messy water cooling and the bodytub unbolts from the self-contained floorpan/chassis, you’re onto a winner.
This is one clever design. It’s unconventional but it all makes sense, it’s robust and parts are easy to come by. There are a few fiddly bits, like rot-prone heater channels within the sills, and expensive heat exchangers to supposedly deliver warmth rather than fumes to the cabin, but mostly a Beetle offers great restoration potential.
Also, of course, you’ll become part of that great aircooled fan base that continues to get stronger ever year.
